[1.31.06]

espeakEVENT_PHONEME, fix audio position of vowel when it follows a voiced consonant.
Ensure enough space in the event list when espeak_Initialize() is called with a small buffer size.
Tone languages: set the final stressed syllable to stress=7 so that it can be longer.
lang=zh: adjust vowels
